In order to identify relevant issues and stakeholders to engage, Suez Environment has developed a methodology and a software to help its managers to build their dialogue road map. While analyzing the local context, the tool allows to map the most critical issues to address and the most relevant stakeholders to engage,  with regard to these specific issues. Analyzing those maps then helps to build an action-oriented dialogue strategy that fits both with the operator’s and stakeholder expectations.

A study concerning the identification of suitable zones for manual drilling has been carried out in 12 countries (Benin, Central African Republic, Chad, Cote d’Ivoire, Liberia, Madagascar, Mali, Mauritania, Niger, Senegal, Sierra Leone, Togo) from 2008 to 2010. The methodology was based in the integration of different information already existing (like maps and data, reports, direct experience of water experts in each country) but not properly organized. All the information was corrected and organized in a GIS database; the cross-analysis of the different layers allowed to identify  the geological suitability (soft and permeable shallow geological layers), the suitability according to water depth (exploitable water not deeper than 25 m) and the most suitable morphological structure.

This solution provides methodologies for addressing water and sanitation issues of low income settlements in Asian cities and its implementation in Tigni, one of the poor settlements in Madhyapur Thimi Municipality, Nepal. In this generalised picture of demand of the services, the focus should go to urban poor. The methodologies developed and tested in mapping the poor, gender assessment and initial environmental examination have come up with appropriate tools for implementing water and sanitation projects in Asia and this will help to meet the objectives of Water for Asian Cities Programme of UNHABITAT.

The method used to assess the flood risk and vulnerability mapping consisted in:

  • Assessing vulnerability-Tools and methods
  • Field Survey and group discussions
  • Mapping for Preparedness
    The mapping was done adopting three different approaches:

-          A geomorphic approach to hazard mapping using geographical information systems (GIS) and remote sensing (RS)

-          Hazard mapping through the measurement of rainfall-runoff processes using US Army Corps of Engineers Hydrological Engineering Corporation’s River System Analysis (HEC-RAS) model

-          Social flood hazard mapping based on local people’s perceptions and experiences

The main sources of information were:

Maps, aerial photographs, satellite images, household survey, group discussions, field observation and published and unpublished documents.

GIS based software such as ArcView, ILWIS, and HEC-GeoRas were used for data processing and analysis.

SUEZ ENVIRONNEMENT’s experience has proven that stakeholder engagement is not only a driver of reputation and license to operate but, above all, a key component of the  successful operation of water and sanitation services. Stakeholder dialogue is critical when it comes to defining services standards, pricing policies, or even CSR programs. In order to identify relevant issues and stakeholders to engage, it has developed a methodology and a software to help its managers to build their dialogue road map. While analyzing the local context, the tool allows to map the most critical issues to address and the most relevant stakeholders to engage,  with regard to these specific issues. Analyzing those maps then helps to build an action-oriented dialogue strategy that fits both with the operator’s and stakeholder expectations.

This research project will undertake to map global vulnerability (current and projected) to selected water-related diseases within a Geographical Information System (GIS) incorporating environmental factors, current burden of illness, socio-economic vulnerabilities and expected impacts of global environmental change.  Factors to be incorporated into the analyses include, but are not limited to: demographics (population growth, density, migration, urbanization); environmental (temperature, precipitation, land use patterns); pathogen etiology and life cycle; access to (safe drinking water, adequate sanitation, public health system); and socio-economic variables (poverty, literacy rates, education levels, community support systems).
